Remote Device Physical Downlink Failure Diagnosis via Coded Signal Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for detecting physical downlink failures in wireless communication systems are inadequate, as they often fail to accurately report information when a failure occurs, leading to instability in the physical uplink and increased complexity in maintenance, requiring on-site testing with dedicated devices.
Innovation Solution
A method where a remote device detects a physical downlink failure, determines a corresponding code, generates a control signal based on an appointed frequency clock, and reports it through the physical uplink to a near-end device, enabling the near-end device to diagnose the failure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the remote device uses existing methods to detect physical downlink failure, then the detection process is simple, but the reported information becomes unstable and unreliable when failure occurs
Solution Approach 1:
The patent introduces an intermediary encoding mechanism where the remote device converts failure detection information into a standardized code format using a pre-stored correspondence table. This intermediary step ensures that even when the physical downlink fails, the reported information maintains stability and reliability through structured encoding rather than direct transmission of raw detection data.
Solution Approach 2:
The patent changes the parameter representation of failure information by converting it from raw detection signals into coded formats based on predetermined correspondence relationships. This parameter transformation ensures that the reported information remains stable and interpretable even under failure conditions, resolving the reliability issue without requiring complex real-time processing.
2Loss of information
If the remote device reports failure information through the physical uplink, then the near-end device can receive the report, but the phase-locked loop loses lock and the uplink becomes unstable
Solution Approach 1:
The patent applies preliminary action by pre-storing the correspondence relationship between information and codes in the remote device before failure occurs. When failure is detected, the device simply retrieves and transmits the pre-prepared code rather than processing information in real-time during the unstable period. This preliminary preparation ensures information can be reported without requiring stable phase-locked loop operation during the failure event.
Solution Approach 2:
The remote device serves itself by maintaining an internal database of information-code correspondences and autonomously selecting the appropriate code based on detected failure conditions. This self-service mechanism eliminates the need for complex real-time communication protocols and reduces dependency on stable uplink conditions for information processing, allowing reliable reporting even when the phase-locked loop is unstable.
3Measurement precision
If maintenance personnel use dedicated test devices to determine downlink failure, then accurate diagnosis is possible, but the maintenance complexity and time increase
Solution Approach 1:
The patent implements a feedback mechanism where the remote device automatically detects physical downlink failure conditions and reports coded information back to the near-end device. This automated feedback loop provides accurate failure diagnosis information without requiring maintenance personnel to perform manual testing, thereby maintaining high measurement precision while significantly reducing the time and complexity of maintenance operations.

AI summary
The present invention discloses a method for diagnosing a physical downlink failure so as to solve the problem in the existing technology of being unable to report information accurately when the physical downlink failure occurs thereby influencing the diagnosis of the physical downlink failure. The method comprises: when a remote device detects the physical downlink failure, determining a code corresponding to information required to be reported based on a stored corresponding relationship between the information and the code; the remote device generating a control signal from the determined code based on an appointed frequency clock; and the remote device reporting a signal corresponding to the control signal to a near-end device through a physical uplink such that the near-end device diagnoses the physical downlink failure according to the reported signal.
